COAL-UN LOADING- DEVICE.

Specication of Letters Patent.

To all whom t may concern:

Be it lmown that I, JAMES H. TU'rwILnR, a citizen of the United States,and a resident of Atlanta -in the county of Fulton and State of eorgia,have invented an Improvement in Coal-Unloading Devices, of which thefollowing is a 'speciication y invention is an improvement 1n coalunloading devices, and has for its object to provide mechanism of thecharacter specifled, comprising end frames adapted to be connected witha coal car and adjustable to various sizes of cars, the said framescarrying a rail, upon whicha carriage 1s mounted to travel from end toend of the rail and the frame, the said carriagel carrying a bucket forreceiving the coal, and a scale for Weighing the bucket and the coal,the bucket being connected to the scale by hoistlng mechanism to permitthe bucket to be raised or lowered.

1n the drawings:

Figure 1 is a front view of the improved unloader. y

F ig. 2 is an end view, with parts 1n sec- FigB is a partial perspectiveview of the top of one of the end frames.

Fig. 4: is a similar view of one end of the rail.

YThe present embodiment of the invention is shown in connection with acoal car 1,' and the improvement comprises two substantially triangularframes adapted for connection with the side of a car, and a s ectionalstandard is provided in connection with each end frame, each standardhaving interlocking engagement with the adjacent frame.

Each end frame is right triangular in form, the three sides being ofangular material, and the hypotenuse side 4 is braced against the angleby an inclined brace 5. 0n the long side 3 is a clamp or clip 6consisting of portions offset laterally with respect to each other andintegrally connected,

and one of the portions is adjustably connected to the side 3 bymeans ofbolts 7 and handle nuts 8. The side 3 is provided with a series ofopenings, to permit the bolts to be connected with di'erent openings, sothat the clamp may be connected with the side at diferent heights, toprovide for varions makes of cars.

. rlhe other portion of the clip or clamp engages over the side of thecar, as shown in 2, with that portion of the said sideA below the clampengaging the outer side of the car and with the side 2 horizontal. Atthe right angle or near the right angle the side 3 is provided with aneye 9, for permitting the attachment of a guy, not shown, for guying theframes. These guys may be stretched across the car or connected With theopposite side of the car, or they may extend in inclined positionlongitudinally of the car side.

For supporting the outer side of each frame a standard is provided, eachstandard consisting of an outer section 10, an inner section l1 and abase 12. The section 11 is mounted to slide in the section 10, bothsections being hollow pipes, and the sections are held inadjustedposition `with respect to each other by means of pins 13, whichare passed through series of registering openings inthe standards. Thebase has engaged with the upper end thereof a screw 13, and this screwhas a plain portion 141 at its upper end which engages within the lowerend of the section 10. The screw is enlarged between the threadedportion and the plain portion, as indicated at 15, and ythis enlargementprovides a shoulder against which the lower end of the outer sectionabuts. rllhe enlargement is also provided with radial openings 16, forpermitting the insertion of a bar to turn the screw to raise or lowerthe section 10 with respect to the base. The upper end of the section 11engages with a depending socket 17, on the outer end of a plate 18 whichis secured to the side 2 at the outer angle of the frame in any suitablemanner, as, for instance, by rivets, as shown. The plate is so arrangedthat the socket depends beyond the frame, and the upper end out thesection 11 is engaged within the socket.

A rail in the form oi an 1-beam 19 rests upon the sides 2 which formsupporting bars and guides for the rail. This rail is provided on itsunder side near each end with a pair of spaced clips 20, which arespaced apart far enough to engage opposite scale indicated generally at23 is supported by the carriage. A pulley 24 is connected with the scaleat the center of the lowerinost beam, and a second -pulley 25 isconnected with a bucket 26 for receiving the coal.

This bucket has a bail 27 which engages the hook of the pulley 25, andthe said pulleys 24: and 25 together with a rope Q8 constitute hoistingapparatus for fraising and lowering the bucket. It will be noticed thatthe bucket when loaded normally does not balance, one side being heavierthan the other, and it is held from dumping by means of hooks 30which'are pivoted to the bucket and engage the bail,-y to hold thebucket in loading position. A pair of wheels 3l is journaled on thebottom of the bucket, on an axle, which is held transversely of thebottom and below the same, for a purpose to be presently described.

In operation, the apparatus is assembled by engaging the clamps 6 overthe side of the car. The standards are adjusted to the proper height andengaged with the sockets 17, after which the rail 19 is properlyarranged. A spirit level 32 is arranged on the carriage, and by means ofthe jacks at the bottoms of the standards, the frames are adjusted untilthe rail 19 is level. The carriage is mounted on the rail, and by meansof the hoisting or block and tackle mechanism the bucket is lowered orraised to the proper height for filling from the car. The coal isshoveled into the bucket, and the said bucket is designed to hold a tonof coal. By means of the scale the coal may be weighed, and by means ofthe carriage the bucket may be moved to the desired point for unloading.The unloading may commence at one end of the car and progress to theother, and by means of the hoisting o1 block and tackle mechanism thebucket may be lowered into the bed of a wagon and moved to the desireddumping point, the bucket rolling upon the wheels 31, and the axleforming a handle for manipulating the bucket.

I claim:

1. A device of the character specified, comprising substantially righttrlangular end frames, each having at one acute angle a socket andhaving on the opposite side a clamp for engaging the side of a car andadjustable longitudinally of the said side, an adjustable standardengaging the socket at its upper end and adapted to rest upon the groundat its lower end, said standard comprising inner and outer sectionsadjustable longitudinally of each other and having means for holdingthem in adjusted position, and a jack base for raising and lowering theinner and outer sections, a rail for connecting the top sides of theframes, said rail having pairs of lugs at its ends for engaging theopposite sides of the end frames, a carriage movable on the rail, ascale supported by the carriage, and

'a bucket having a block and tackle connection with the scale.

2. An apparatus substantially as herein described, comprising uprightshaving means whereby they may be vertically adjusted and cross framescorresponding to said uprights and having at thelrv outer upper endsmeans for interlocking engagement with the upper ends of the uprights,said cross frames also having top bars constituting rails and uprightbars having.

means for engagement with the side of a car and adapted for detachableengagement therewith, a beam traveling on the top bars or rails of saidcross frames, a carriage traveling on the beam, and a bucket suspendedfrom the carriage, all as and for the purpose set forth. JAMES H.TUTW'ILER.
